REGISTER PUNCH MECHANISM AND LIKE DEVICE D. D. VANDERCOOK Filed April ll. 1927 @MW-@Mg Patented Jan, 20, 1931 Y UNITED STATES CHICAGO, ILLINOIS, A PARTNERSHIP REGISTER-PUNCH MncHAN-ISM AND LIKE DEVICE Application filed April 11,

My invention relates to register punch mechanism and like devices for use in connection with printing presses.

One of the objects of the invention is to provide a simple, practical and advantageous legiister punch mechanism of the class speci- Another object of the invention is to provide a register punch'mechanism which will secure accuracy by simple, readily operated and inexpensive devices.

In the accompanying drawings: Fig. 1 is a vertical section of a register punch mechanism embodying my invention.

Fig. 2 is a plan view of the same. Fig. 3 is a vertical section of an end portion of the device on an enlarged scale.

Fig. 4 is a section of the portion of the device shown in Fig. 3 but at right angles to the section ofFig. 3 and Fig. 5 is a horizontal section of the mechanism shown in Fig. 4.

Referring to the drawings, I show a device having a suitable frame 1 provided with 2B a bed or support 2 upon which a copper plate 3 or like device to be punched maybe placed.

I also show microscope 5 supported at one end of the base 1, as by an upright or standard 6, mounted on said base 1. As a 3o preferred arrangement a plate 7 is secured as by the screw 8 to the top of standard 6 and plate 7 has an aperture in which the lower end of the microscope 5 may be fitted. Upright 6 is preferably provided with a side opening 9 adapted to admit light below the microscope to assist visibility. An end piece 10 is fitted into standard 6 so that its lower .end is justabove and adapted to be in contact with end of plate 3 to be punched.

The lower end of member' 10 is provided with a punch opening 11 adapted to receive the punch after the same has passed through plate 3.l Said member is also preferably provided with a side light opening 12 adapted to `4J! admit light in proximity to the marking on the plate 3 so as to insure good sight of said plate 3 and is mounted to be raised and lowered so as to punch an aperture in sai-d plate said member 22 'beingmomaed on ai pivot 24. Member y16 slides in a gu'ideway formed byA sides or cheeks 25 on "Standard .6. j

' Thus in operation the plate may be adjusted in such position thatfthe hairmarks26 will bev'isible through microscope 5 and by means 'of the microscope and lthe fact that it receivessuch an abundance of light, the adjustmentof plate Bfmay be absolutely accurate. At this ltime handle 23 is operated'so as to elevate holder 16,'and thereby cause punch 15 to pass upwardly Vthrough plate 3 and `rthis punching operation shall take place at exactly "the right"point,` Handle 23 shallV then be operated so as to lower holder 16 and purich 15,`after 'which lpl'ate Sfmay be turned endpfor end and the otheien-d punched in a similar manner. Itfw'ill `be 'seen tha'tthe device is extremely accurate and "inexpensive yand readily operated. 4

cations may befmade without departing from the spirit of the invention. y What-Ifclaim is zl 1. A register punch mechanismfco'mpris- "ing fa microscope. and holder for holding the same above an article to be punched, in com-v bination w'ltha diie and a punch arranged 'Itis understood 'that 'changes yand mo'dili- PATENTDFFICE DAVID D. vANDERcoox, or CHICAGO,` ILLINOIS, AssIGNoR To vANDnRcooiI a "sous, on f below the microscope and in vertical alignment therewith,gV ar vertically -reciprocable holder carryingthe `punch,and vmeans for'` `actuating saidhol'der so as lto force the punch upwardly lthrou'tgh said article and die,

2.

holder for a microscope having a side opening for the admission of light, saidholder being arranged to hold the microscope over the die and in vertical alignment therewith, said vside opening being adapt-ed to admit' light to the die.

4. In a mechanism ofthe class specified, the i combination with a punch and die, of a holder for a microscope havingtwo side openings for the admission of light, said openings facing at right angles to one another, said holder being arranged to hold the microscope over the die and in vertical alignment therewith, said side openings being adapted to admit light to the die.

5. In a mechanism of the class specified, `the combination witha punch and die offa holder fora microscope having two'side openings for the admission of light, said lopenings facing at right angles to oneanother and being one above the other, said holder being adapted to hold the microscopeso that the article to be punched may be seen through the die and said side openings being adapted to admit light to the die. Y

6. In a mechanism of the class specified, the combination with a punch and die, of a holder for ay microscope having two side openings for the admission of light, said openings facing at right angles to one another and being one above the other, the low. er opening being substantiallv at the surface of an article to be punched, said holder being adapted to hold the microscope Yso that the article to be punched ma;7 be seen through the die and said side openings being adapted to admit light to t-he die.,

8. A device of the class specitiedcomprising a work holder, a sighting device, and marking mechanism comprising a member having an aperture adapted to serve as a light-admitting` opening for -thevsighting device and also to serve as a. die, and a punch arranged on the side of the work opposite the sighting device and said aperture and adapted to cooperate with thelatter.

9. A device of the class specified having a work holder, a. sighting device in the form of 4a microscope mounted above therwork holder, and marking mechanism comprising a punch and die, one of which. is arranged on one side of the work on the holder, and the other arranged on the other side thereof, said DAVID D. VANDERCOOK.
